发明名称 Multiple-tone display system
摘要 A dot matrix display system for multiple-tone displays, including a display device in which pixels are arrayed in a matrix shape, an LC (liquid-crystal) drive signal generator which converts color display data into LC display data, an 8-level data driver which selects one of 8-level voltages in accordance with the LC display data and then delivers the selected voltage, and an 8-level voltage generator by which the 8-level applied LC voltages to be applied to the pixels are produced so as to substantially make uniform color differences between the respectively adjacent tones of the multiple-tone displays. Owing to the substantially uniform color differences between the respectively adjacent tones, multiple-tone displays which are uniformly seen by the human eye can be obtained.
